OC AI Builders Lightning Hackathon
What can you build with AI in 50 minutes? Come find out—and show the room what you made.
The format is simple: you get 50 minutes to build something with AI, then up to 2 minutes to demo it. Come with an idea or start from scratch. Build solo or form a small team when you arrive. Rough, weird, incomplete experiments are welcome—the point is to make something real, show it, and trade notes.
FORMAT
• 50 minutes to build
• 2 minutes to demo
• Solo builders and small teams are welcome
• A small working slice beats a pitch deck
AGENDA
• 5:00–5:30 PM — Arrival, food, drinks, and networking
• 5:30–5:40 PM — Welcome, format, and team-up
• 5:40–6:30 PM — 50-minute build sprint
• 6:30–7:20 PM — Two-minute demos
• 7:20–8:00 PM — Food, drinks, networking, and follow-ups
WHAT CAN YOU BUILD?
Agents, apps, workflow automations, evals, developer tools, product experiments, useful AI-powered systems—or something we have not thought of yet.
WHO SHOULD ATTEND
• Engineers and founders building with AI
• Product and operations people turning AI experiments into real workflows
• Curious builders who want candid technical discussion, not a sales pitch
WHAT TO BRING
Bring a laptop, charger, an idea if you have one, and a willingness to ship something small. Food and drinks will be provided.
